High-performance low-bandgap conjugated polymers bearing diethynylanthracene units for thin-film transistors

초록

Novel donor-acceptor pi-conjugated copolymers, P(DPP-BDT) and P(DPP-ANT), were synthesized in 87-89% yield. Thin-film transistors (TFTs) made from the thermally annealed film of P(DPP-ANT) exhibited much better performance (e.g., mu(max) = 1.90 cm(2) V-1 s(-1), I-on/off approximate to 10(6)) than those made from the thermally annealed film of P(DPP-BDT).
